what matters should be paid attention to in the incombustibility test of building materials? the non-combustibility test furnace for building materials is suitable for specifying test methods for evaluating the burning performance of building materials under laboratory conditions. classification of combustion performance of building materials and products is cccording to the national standard en13501-1:2007, which are divided into four grades of building materials and components: a, b1, b2, and b3, corresponding to non-combustible, flame retardant, combustible and flammable materials or products. among them, the non-combustibility test furnace of building materials determines whether the building materials are non-combustible under specified conditions, and is used in the non-combustibility test of building materials.

¿Qué debe notarse en el horno de ensayo no inflamable de materiales de construcción? Las notas son las siguientes:
1. El Equipo controlado por ordenador protegerá contra los virus.
Nbsp;
2. Equipar el equipo de extinción de incendios.
Nbsp;
3. Al final del ensayo, todas las fuentes de alimentación y aire deben apagarse.
Nbsp;
4. Utilizando la tensión especificada, el instrumento debe tener un cable de tierra.
Nbsp;
5. Cuando se prueban las muestras, algunos materiales liberan gases tóxicos y peligrosos. Se recomienda probar en el armario de ventilación y hacer un buen trabajo de protección personal.
Nbsp;
6. Durante el ensayo, el operador no debe abandonar el lugar de ensayo.
